When trying to be heard over noise, humans and other animals raise their voices
Earth & Environment
The "third rock from the Sun"—Earth. With an orbit neither too close nor too far from the Sun, it occupies a unique position in the Solar System. It's the only planet known to man with the right conditions for the origin and evolution of life. During Earth's 4.5 billion-year history, a combination of processes has transformed it into a watery blue, living planet. The Earth's ecosystems involve complex interactions between the biological (living) and physical (non-living) worlds. Scientific research helps us comprehend our effects on the environment and how the environment in turn responds to impacts of our activities.
In this week's episode, we discover why freshwater lakes are becoming saltier and the role temperature plays in the spread of mosquito-borne diseases, explore a new device for combatting Parkinson's disease, and finally, learn how to excite girls about STEM
The new TexNet Seismic Monitoring Network is helping to locate and determine the origins of earthquakes in Texas
Humans are adding carbon dioxide to the atmosphere by burning fossil fuels and deforestation. Through a process called ocean acidification, about a quarter to a third of this carbon dioxide is absorbed by the ocean, causing a decrease in the pH of ocean water
In some areas--China's Yellow River, for example--huge sediment loads can clog the flow of a river, thereby causing floods
Marine ecologist Brian Beal and a team based at the University of Maine at Machias Marine Science Field Station at the Downeast Institute are putting their aquaculture innovation skills to work
Mike Gil, a postdoctoral scholar at University of California-Davis, will be one of 20 international fellows who will give talks at TEDGlobal in Arusha, Tanzania, in August
Each year 12 competitively selected undergraduates fly to Australia to work alongside PIRE researchers as they conduct field work to look at engineering, ecological, and social science aspects of Melbourne's green storm water infrastructure
With support from the National Science Foundation (NSF), Masters and a team at the University of Florida are developing a world-class facility with new technology to help engineers and scientists better understand the high-wind storms that batter communities along U.S. coastlines
If a Pacific parrotlet needs to get to a nearby branch, it uses its legs to jump. If a target falls just outside of its jump range, however, it can add a "proto-wingbeat," a small flapping motion that allows it to travel farther without using as much energy as full flight.
Research consistently shows that children who have opportunities to actively investigate natural settings and engage in problem-based learning greatly benefit from the experiences
The annual migration of some beluga whales in Alaska is altered by sea-ice changes in the Arctic, while other belugas do not appear to be affected
Lisa Porter, professor of materials science and engineering at Carnegie-Mellon University, discusses her research on semiconductor materials and devices, especially those that enable new technologies for a more energy-efficient future.
Jellyfish and eels may seem like weak and useless creatures, but what if the process of evolution shaped them to move through the water using little to no energy?
Anish Tuteja and his research group have created a self-healing, water-repellent spray-on coating
Node by node, engineer Zhaohui Wang has a plan for improving underwater acoustics networks to maximize information delivery
Imprint Energy, a small business funded by the National Science Foundation, is pioneering a new way to manufacture ultrathin, flexible, high-density batteries.
An NSF-funded research team at the University of Oklahoma's Advanced Radar Research Center hopes that their radar simulator can assist researchers and meteorologists in better understanding how debris interacts with deadly tornadoes.
Maine's Sustainable Ecological Aquaculture Network (SEANET) helps support University of Maine research and educational outreach related to the farming of aquatic organisms
An international team of paleontologists from the United States, China, Japan, Russia and Mongolia has discovered a new extinct species of plant from the Early Cretaceous that appears to be distantly related to living Ginkgo biloba
